WILLIAM L. BURNER, OF KorrnL, Ann OSCAR E. KAN'JTZENWEIN, OF'NEWCASlLLE r nNsYLvAnIA, AssIeNons 'IO KOPPEL INDUSTRIAL CAR, AND EQUIPMENT COM IEANY, OF PITTSBURGH, PENNSYLVANIA, A. CORPORATION OF PENNSYLVANIA DOOR FOR DUMP CARS.

Application filed March 28, 1925. Serial No. 19,021.

This invention relates to dump cars, and more particularly to that type of dump car in which the side wall'of the car body comprises a single or a plurality of movable doors, and has for an object the provision of a door for such a car which when bent or bowed outwardly, due to the weight of the lading or otherwise, may be removed from the car body and reversed end for end, and again attached to the car body to present the bent or bowed portions inwardly, so that when lading is again placed in the body it will have a tendency to force the bowed portion outwardly to its original condition.

Another object of the invention is to provide each side of a dump car with a movable door, which doors when they become accidentally bent or bowed outwardly, may be removed from the car and one substituted for the other to present the bowed portions inwardly, so that when the body is again loaded the weight of the lading will tendto straighten both of said doors.

A further object of the invention is to provide novel stiffening means for the central portion of a discharge door so that any bending of the door will be gradual.

Referring to drawings in which like reference characters refer to like parts, Fig. 1 is a plan View of a portion of a car embodying the invention, the sides of the body being shown, in dot and dash lines, bent or bowed outwardly; Fig. 2 is a like view showing, in dot and dash lines, the side doors reversed and the bowed portions presented inwardly; Fig. 3 is an enlarged end view of the car embodying the invention; Fig. 4 is an enlarged face view of one of the side doors of the car, portions of the door being broken away; Fig. 5 is an end view of the same, and Fig. 6 is a sectional View of the same taken on the line 66 of Fig. 4.

Referring now in detail to the drawings, the reference character 1 indicates a dump car body, which in the present embodiment of the invention, is tiltably mounted on an underframeQ, adapted to discharge thelad ing carried by the body to one side or the other of the railroad track rails. The car body comprises a floor 3, end walls 4, and

otally connected with the end walls. Each r of these doors comprises an inner plate'6, and an outer plate 7 which plates are spaced apart throughout their length.- Between the upper portions of these plates a member 8 is provided which is preferably of channel form, having its web disposed horizontally, and forming the top member of the door, and having its flanges 9 depending downwardly and secured to the plates 6 and 7. Between the lower portions of the'plates 6 and 7 a member 10 is provided, which is preferably of channel form, having its web 11 disposed horizontally, and its flanges 12 disposed downwardly and secured to the plates, this member forming the bottom member of the door.

Each end of each door is provided with a channel shaped member 13, having its flanges directed inwardly and secured to the plates 6 and 7, and to the top and bottom members 8 and 10, respectively of the door. The web 14 of this member is provided with perforations 15, one of which is located adjacent the top edge of the door and the other ad jacent the lower edge of the door, and both 1 being located centrally of the thickness of the door. Between the perforations 15 the central portion of a member 16 is secured to the web 14, the end portions 17 being offset and provided with perforations, each of which. registers with one of the perforations 15. The space adjacent the upper edge of the door is for the reception of one end of a bar 18, which end is provided with a perforation adapted to register with the perforation 15, and the perforation in one of the offset portions 17, and when theseperforations are in registration a pin 19 is passed through them, thus connecting the bar and door together. The other end of the bar 18 is pivotally connected with the end wall 4 of the body through the medium of a pin 20.

In the space adjacent the lower edge of the door, one end of a bar 21 is mounted on a pin 22, which is passed through the adjacent perforation 15, and the perforation in the lower oflset portion 17. The opposite end of this bar is connected with the bar 18 through the medium of a pin 23.

On each side of the center of the length of the door, and between the plates 6 and 7 a vertically disposed member24 is provided, which is'preferably of channel form, havingits flanges 25 secured to the plates 6 and 7. Between the plates 6 and 7, and between the members 24, and intermediate the top and bottom members 8 and 10, respectively of the door, a member 26 is provided which is preferably of channel form, having its web 27 disposed horizontally and its flanges 28 depending downwardly, which flanges are secured to the plates 6 and 7. The ends of the member 26 are connected with the members 24 through the medium of angular members 29, one flange of each of which is secured to a web 27 of the member 26, and the other flange is secured to a web of one of the members 24. It will here be noted that the door, as a whole, is so constructed and stiflened that any tendency of the door to bend or bow will be a gradual one from end to end, and not a sudden bending or bowing at the center of the length of the door.

It will also be noted that when the doors are bent or bowed outwardly, as shown by dot and dash lines in Fi 1 of the drawings, and do not come bac to their original condition when the lading is discharged, the pins 19 and 22 are removed, and as both ends of the door are substantially identical the door is turned end for end and again connected to the bars 18 and 21 by means of the'pins 19 and 22, thus the portion of the door which was bent or bowed outwardly will be presented inwardly, as shown by dot and dash lines in Fig. 2, so that when the car is again loaded the lading will have a tendency to force such bent or bowed portion outwardly to its original condition. In some cases it may be desired to substitute one door for the other so that the outwardly bent or bowed portions of the doors will be presented inwardly, and further it may be desiredto turn the door so that the portion thereof, which was the top of the door, will be the bottom, and vice versa.

In a car of the type just described the body of the car tilts toward one side or the other, while the door is supported or slightly raised from its normal closed position, and in the present embodiment of the invention a bar is provided for supporting the door, the upper end of such bar being pivotally connected with the bar 18, the lower end of such bar (not shown) being suitably connected with the car or suitable operating mechanism. 1

It will be apparent to those skilled in the art to which this invention appertains that changes may be made in the details of the invention without departing from the spirit and scope of the appended claims.

Having thus described the invention, what we claim as new and desire to secure by Letters Patent is 1. A discharge door for dump cars which when bowed outwardly may be reversed to present the bowed portion inwardly, and means whereby the bowing of the door will be gradual.

2. A discharge door for the side of a dump car which when bowed outwardly may be reversed end for end to present the bowed portion inwardly, and means whereby the bowing 0t the-door will be gradual. Y

3. In a dump car, a discharge door, and channel shaped means terminating short of the ends of said door for stiffening it about the center of its length so that any bowing of the door will be gradual.
